CVE-2021-41091 | 2 Fedoraproject, Mobyproject | 2 Fedora, Moby | 2024-11-21 | 4.6 MEDIUM | 6.3 MEDIUM |
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade limit access to the host to trusted users. Limit access to host volumes to trusted containers. | |||||
CVE-2021-41089 | 2 Fedoraproject, Mobyproject | 2 Fedora, Moby | 2024-11-21 | 4.4 MEDIUM | 2.8 LOW |
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted. | |||||
CVE-2021-32847 | 1 Mobyproject | 1 Hyperkit | 2024-11-21 | N/A | 7.1 HIGH |
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior, a malicious guest can trigger a vulnerability in the host by abusing the disk driver that may lead to the disclosure of the host memory into the virtualized guest. This issue is fixed in commit cf60095a4d8c3cb2e182a14415467afd356e982f. | |||||
CVE-2021-32846 | 1 Mobyproject | 1 Hyperkit | 2024-11-21 | N/A | 7.7 HIGH |
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107, function `pci_vtsock_proc_tx` in `virtio-sock` can lead to to uninitialized memory use. In this situation, there is a check for the return value to be less or equal to `VTSOCK_MAXSEGS`, but that check is not sufficient because the function can return `-1` if it finds an error it cannot recover from. Moreover, the negative return value will be used by `iovec_pull` in a while condition that can further lead to more corruption because the function is not designed to handle a negative `iov_len`. This issue may lead to a guest crashing the host causing a denial of service and, under certain circumstance, memory corruption. This issue is fixed in commit af5eba2360a7351c08dfd9767d9be863a50ebaba. | |||||
CVE-2021-32845 | 1 Mobyproject | 1 Hyperkit | 2024-11-21 | N/A | 7.7 HIGH |
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior of HyperKit, the implementation of `qnotify` at `pci_vtrnd_notify` fails to check the return value of `vq_getchain`. This leads to `struct iovec iov;` being uninitialized and used to read memory in `len = (int) read(sc->vrsc_fd, iov.iov_base, iov.iov_len);` when an attacker is able to make `vq_getchain` fail. This issue may lead to a guest crashing the host causing a denial of service and, under certain circumstance, memory corruption. This issue is fixed in commit 41272a980197917df8e58ff90642d14dec8fe948. | |||||
CVE-2021-32844 | 1 Mobyproject | 1 Hyperkit | 2024-11-21 | N/A | 6.2 MEDIUM |
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior of HyperKit, ` vi_pci_write` has is a call to `vc_cfgwrite` that does not check for null which when called makes the host crash. This issue may lead to a guest crashing the host causing a denial of service. This issue is fixed in commit 451558fe8aaa8b24e02e34106e3bb9fe41d7ad13. | |||||
CVE-2021-32843 | 1 Mobyproject | 1 Hyperkit | 2024-11-21 | N/A | 6.2 MEDIUM |
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior of HyperKit, `virtio.c` has is a call to `vc_cfgread` that does not check for null which when called makes the host crash. This issue may lead to a guest crashing the host causing a denial of service. This issue is fixed in commit df0e46c7dbfd81a957d85e449ba41b52f6f7beb4. | |||||
CVE-2018-12608 | 1 Mobyproject | 1 Moby | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
An issue was discovered in Docker Moby before 17.06.0. The Docker engine validated a client TLS certificate using both the configured client CA root certificate and all system roots on non-Windows systems. This allowed a client with any domain validated certificate signed by a system-trusted root CA (as opposed to one signed by the configured CA root certificate) to authenticate. | |||||
CVE-2018-10892 | 4 Docker, Mobyproject, Opensuse and 1 more | 6 Docker, Moby, Leap and 3 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
The default OCI linux spec in oci/defaults{_linux}.go in Docker/Moby from 1.11 to current does not block /proc/acpi pathnames. The flaw allows an attacker to modify host's hardware like enabling/disabling bluetooth or turning up/down keyboard brightness. |
